37 * SM_ENTRY - State machine function entry point
38 * @machine: State machine name
39 * @state: State machine state
41 * This macro is used inside each state machine function declared with
44 * information about state transition and update the state machine state.

55 * SM_ENTRY_M - State machine function entry point for state machine group
56 * @machine: State machine name
57 * @_state: State machine state
60 * This macro is like SM_ENTRY, but for state machine groups that use a shared
61 * data structure for more than one state machine. Both machine and prefix
62 * parameters are set to "sub-state machine" name. prefix is used to allow more

93 * SM_ENTER - Enter a new state machine state
94 * @machine: State machine name
95 * @state: State machine state
97 * This macro expands to a function call to a state machine function defined
